Question

Write the slope-intercept form of the equation of the line through the given point with the given

slope. through: (1,4), slope = 9

Answer 1

y = 9x - 5

Explanation:

The slope is already given, so we just need to find the y-intercept.

Plug in 9 for m, 1 for x, and 4 for y in the equation y = mx + b.

4 = 9(1) + b

b = -5

Now that we know the y-intercept, we can construct the equation of the line.

y = 9x - 5
